India’s income tax system offers two choices and tax payer has to evaluate New Tax Regime vs. Old Tax Regime, to opt for the best option for him/her.
Introduced in Budget 2020, the New Tax Regime aims for simplified compliance with lower rates but fewer deductions. Budgets 2023 and 2024 enhanced it further—making it the default option from AY 2024–25 onward.
This guide explains key differences between New Tax Regime vs. Old Tax Regime i.e. slab rates, deductions, recent updates, and tips for choosing wisely.
What is the Old Tax Regime?
The Old Tax Regime follows traditional slab rates but allows taxpayers to claim multiple exemptions and deductions:
- Standard Deduction
- House Rent Allowance (HRA)
- Leave Travel Allowance (LTA)
- Section 80C investments (LIC, PPF, ELSS)
- Section 80D (Health Insurance Premiums)
- Home loan interest (Section 24)
Ideal for taxpayers who can maximize deductions to reduce taxable income.
What is the New Tax Regime?
The New Tax Regime offers lower, simplified slab rates but removes most deductions and exemptions.
- Designed for ease of filing.
- Default from AY 2024–25 (income earned in FY 2023–24 onward).
- Taxpayers can still opt for the Old Regime when filing.
